Samsung has recently announced to release Galaxy Note 4 in next month only for South Korean Markets. There are two variants of this Note 4 and they differ in processing unit. Many markets have it with Qualcomm Snapdragon 805 APQ8084 which is a 2.7GHz quad core Krait 450 part whereas others are getting it with Samsung's Exynos 5433 which has four Cortex-A53 cores and four Cortex-A57 cores in a big. LITTLE configuration.
Now this third version of Galaxy Note 4 is coming with Qualcomm Snapdragon 810 that is like Exynos 5433 supporting four Cortex- A53 and four Cortex –A57 cores with LITTLE configuration. Samsung is advertising the speed the new Galaxy Note 4 will have and is not talking about system on chip. Snapdragon 810 generates 3x20MHz carrier aggregation boosting LTE speed to 450Mbps on future Category 9 LTE networks and 300Mbps on category 6 LTE networks.
In other aspects this Galaxy Note 4 is the same smartphone already launched earlier. However this model will remain restricted to South Korean markets; at least as the rumor goes at present. However, as it happened with Galaxy S5 LTE-A, the new Galaxy Note 4 can reach other places as well. Let us wait and see what exactly comes out in the actual scenario.
